1. CE 120 Class Project

2. Design Historic Bridges – Architecture – Simple forces analysis

4. About SketchUp SketchUp users are architects, designers, builders, makers and engineers. They are the people who shape the physical world. They are important, and they deserve great tools because great tools produce great work. Great tools are ones you look forward to using. They do one thing (or maybe two) really, really well. They let you do what you want without having to figure out how. They help with hard or boring tasks so that you can focus on being creative, or productive, or both. And they are, in their own way, beautiful. At SketchUp, “we” do our best to make great tools for drawing. For our users, drawing is thinking. They draw to explore ideas, to figure things out, to show other people what they mean. They draw because they love it, and because nothing great was ever built that didn't start with a great drawing.

6. Schedule Select bridge and send location and pictures to professor by 4pm, Feb 12. No interim report or plan due You set your own schedule Waiting is costly and will result in inferior performance Stick to the schedule (learn how to set your own priorities) Present on last class day Submit files by last class day

7. Deliverable requirements sketchup and forceeffect files Powerpoint presentation

8. Teams Teams of 4 (sometimes 3) You will receive and email with the names and contact info for those on your team You choose a leader/organizer In consultation with your leader, choose roles for all team members Students will anonymously rate each other’s contribution and will figure into grade

9. FORCE EFFECT I would like you all to do a little research on forces acting on a bridge. You should make some reasonable assumptions after doing this research, and apply the loads in places that are supported by your research and reasonable assumptions. This is part of the exercise. It is intentionally open-ended and requires you to use judgment. I won’t be too critical in grading as long as you take it seriously.

10. Submitting your files Please submit your sketchup file (.skp) forceeffect files and power point for your presentations to me via email by midnight Tuesday before the presentation or earlier if possible. If either file is too big to email, you can send them to me using a service such as bigfiles.com. Please make sure you get a response from me that I have your file (you can send a separate email with no attachment and if I get that but not your attachments, I will let you know. Important: name your file(s) starting with GROUPXX where XX is your group number, 01 to 09. You can add more to the name, but please start them with GroupXX so I can sort them for fast access during class.

11. For the presentations, you need to have a power point presentation with one page each on: – Title slide – Team members and roles – Name of bridge you selected with location map and picture of bridge, highway route or railroad name – Some details about the bridge – type (truss, suspension), purpose (rail, highway, both), when built, dimensions (number of lanes/tracks, width, height, length, height above river or ground, anything special about it, any notable damage to it in the past, etc. – Sketchup plan – Sketchup profile – Sketchup perspective (what it looks like from an angle) – Sketchup ddriver’s view (what it looks like to a driver going across) – Forceeffect slide showing applied loads – Forceeffect slide showing resulting forces and diagrams (can be a few slides). – Thank you/Contact information slide (names and email addresses)

12. After presenting your power point, one person should quickly demo their Sketchup and another should demo the forceeffect. Each person on the team needs to present part of the slideshow. If 3 people, that’s about 4 slides each. You should state who you are when you start your part of the presentation. You should not go back and forth. E.g., one person does slides 1-3, second person does slides 4-6, etc. You don’t all have to do the same number of slides, just about the same amount of time (some slides take longer than others.) We will have to be very strict on time to get this done in 105 minutes. You should shoot for 2 minutes each person. That will allow for a quick question or two and transition between groups. We will have the next group waiting in the hall to speed things up. I need to stress that you should practice to get the presentation length right. It is very difficult to do something meaningful in 2 minutes. You may wish to split it up by having two people do the slides and two different people do the demos. Again, two minutes only for each person.

13. Peer Evaluation You will be provided a form to evaluate the people in your own group for contributions to the project; this will be taken into consideration in grading. Everyone will rate other group presentations. I will prepare the rating questions and have them ready for you at the beginning of the presentations. You SHOULD NOT rate your own group or the group going ahead of you (while you are “on deck”). Turning this will contribute toward your grade as well.
